The SANYO DENKI San Ace Oil-Proof Fan has earned its title as the "guardian" of machine tools by solving the two most critical challenges in machining environments: oil mist erosion and overheating of precision components.
In environments such as CNC machines and machining centers, mist from cutting oil and coolant is ubiquitous. Ordinary cooling fans are easily penetrated by this mist, leading to internal coil short circuits, bearing jams, or electronic component failures. The SANYO DENKI San Ace Oil-Proof Fan provides comprehensive protection for machine tools through the following core advantages:
1. Special "Oil-Proof Armor" Design
This is the fundamental reason for its role as a "guardian."
（1）Oil-Resistant Materials: The fan's impeller, magnets, and key sealing components are manufactured from special oil-resistant materials. This is akin to outfitting the fan with a hazmat suit, effectively resisting chemical erosion from cutting oil mist and coolant, preventing oil contamination from penetrating the motor interior.
（2）Sealed Construction: A specialized sealing structure is designed for high-oil-mist environments to protect internal windings and electronic components, ensuring stable operation even in harsh industrial conditions.
2. Ultimate Durability and Long Life
In machines requiring 24/7 continuous operation, the fan's lifespan directly determines maintenance costs.
（1）Extended Lifespan: Even in high-temperature (60°C) and oil-mist environments, the expected lifespan can reach 40,000 hours or more (up to 70,000 hours at 40°C).
（2）Reduced Downtime: This means maintenance cycles can be significantly extended (case studies show maintenance frequency extending from 1.5 years to 4.5 years), greatly reducing the number of machine stoppages due to fan failure and safeguarding production efficiency.
3. High Static Pressure and Efficient Cooling
Machine tool interiors are compact, often requiring airflow to overcome resistance from long ducts or dense electronic components.
（1）Powerful Airflow: San Ace Oil-Proof Fans (such as the 9WFA series) are specifically designed for high static pressure. For example, they maintain stable airflow even in systems with long ventilation ducts or high resistance, rapidly dissipating heat generated by electrical cabinets, servo drives, or main spindle controllers.
（2）Prevents Overheating: Through efficient heat dissipation, it prevents damage to the machine tool's core electronic components caused by overheating, ensuring machining accuracy and equipment stability.
4. Smart Monitoring and Reliability
Status Monitoring: Many models are equipped with a Pulse sensor to monitor fan speed in real-time. If the fan stops abnormally, the system can trigger an alarm immediately, preventing the burning of expensive machine tool motherboards due to cooling failure.
Core Series Comparison: Guardians for Different Scenarios
Depending on the specific requirements of your machine tool equipment, you can select the appropriate "guardian" series:
Series | Features | Applications |
9WF Series | General Oil-Proof. Balances performance and cost with a wide range of sizes (including 120mm large sizes). | Suitable for general industrial equipment, basic cooling for CNC machines, and larger electrical cabinets. |
9WFA Series | High Static Pressure Oil-Proof. Designed for high oil concentration and high-resistance environments with enhanced durability. | Ideal for machining centers with long ventilation ducts, extremely high oil mist concentration, or core control systems requiring high reliability. |
Waterproof Series (e.g., 160AD) | Waterproof & Dustproof. Features IP56 or higher protection ratings. | Suitable for special locations exposed to coolant splashes or outdoor/harsh environment machine tools. |
Summary
The SANYO DENKI San Ace Oil-Proof Fan resists erosion through oil-resistant materials, ensures cooling efficiency through high static pressure, and reduces maintenance risks through long-life design.
It does more than just exhaust heat; it protects the expensive electronic components within machine tools through stable and reliable operation, truly earning its title as the machine tool's "guardian."
